3.3.7 BUS Customer Units, SK CU1-CAN-RJ, SK CU1-PBR
(SK CU1-CAN-RJ, Part No.: 278200052)
(SK CU1-PBR,
Part No.: 278200030)
In addition to data connections, all Bus customer units also
provide conventional digital inputs and outputs.
By means of a relay contact, brake control can be actuated or
warnings can be sent to another system. The digital input has
a 2.5V switching threshold for the evaluation of the
temperature sensor. The input can, however, also be used for
an emergency stop function.
All BUS switching components have the same basic design.
However, the Profibus option has an RTS signal output on
connector X6.3.83 in addition to the data leads. In addition, the
Profibus module also has a second set of data connections
(X6.4) and a DIP switch for the termination resistors at the
front.
Note: Further details can be found in the relevant special
operating instructions for the bus systems.
